摘要：An ultrasensitive cysteine sensor is prepared by using a Nafion assembly of a CdS quantum dot-methyl viologen complex on a conductive ITO surface. It is effective in the readout of the photoelectrochemical response to cysteine with high sensitivity, good selectivity, and fast response. ? 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
